Combine onion, bell pepper, beef and garlic in a large Dutch oven over medium-high heat. Cook for 5 minutes or until beef is browned, stirring to crumble. Stir in chili powder, cumin, sugar and salt; cook 1 minute. Add oregano, kidney beans, tomatoes, broth and beer to pan; bring to a boil. Reduce heat and simmer. The longer you simmer, the more the flavours will mingle. Five minutes before you want to serve, stir in cornmeal and cook. Stir in lime juice and serve.
